已经证明，用过渡族金属激活的氧化物荧光体作为场致发光器件的发光层以获得三基色，是有前途的。例如，发红光用Ｃｒ，发绿光用Ｍｎ与发蓝光用Ｔｉ。也已证明ＺｎＡｌ２Ｏ４：Ｍｎ或Ｚｎ２ＳｉＯ４∶ＭｎＴＦＥＬ器件发出的绿光，Ｚｎ－Ｃａ２Ｏ４∶ＣｒＴＦＥＬ器件发出的红光与Ｚｎ２ＳｉＯ４∶Ｔｉ发出的蓝光均具有高亮度，适于用作全彩色ＴＦＥＬ显示器的三基色。 It has proven promising to use transition metal activated oxide phosphors as the light-emitting layer of electroluminescent devices to obtain the three primary colors. For example, Cr for red light, Mn for green light and Ti for blue light. It has also been demonstrated that the green light emitted by the ZnAl 2 O 4: Mn or Zn 2 SiO 4: MnTFEL device, the red light emitted by the Zn-Ca 2 O 4: CrTFEL device, and the blue light emitted by the Zn 2 SiO 4: Ti have high brightness and are suitable for the three primary colors of the full color TFEL display.
